Figure 2: Simplified diagram showing the hydraulic remining of tailings. It can be noted that the use of hydraulic mining for tailings can be to either reprocess the waste, mine the waste as a product, or for moving of the tailings to a more suitable location.
Producers of all sizes depend on our solutions to achieve continuous, efficient operations in dewatering, thickening, and tailings. Examples range from worldleading companies like Exxaro, Anglo Coal, and Jindal, to many local mines in South Africa, Europe, and the Americas.
Findings: Current practise at Australian coal preparation plants is to thicken fine coal tailings with highrate thickeners utilising high molecular weight polymeric flocculants. The thickener underflow is either dewatered further or disposed of.
Sep 01, 2009· Level measurement equipment is part of almost every process in a coal mine. You hardly see the instruments but they are there and make a huge difference when it comes to efficiency, safety and automated control of the plant. All mining concentrators and coal preparation plants have tailings thickeners.
The methods commonly employed for disposal of these wastes in each of the industry segments (that is, coal mining and metalore and nonmetal mineral mining) are described below. Mining Coal Tailings Disposal As has been pointed out earlier in this section, immense quantities of wastes are produced by coal mining activities.
The range of activities we have been involved with includes consideration of integration of other mine wastes (such as codisposal for coal tailings, placement of course and fine rejects) to develop robust solutions (such as dry stacking), and also modification of tailings and ponds by thickening (paste) or chemical modification to achieve ...
Level measurement equipment is part of almost every process in a coal mine.

All mining concentrators and coal preparation plants have tailings thickeners. These instruments treat the
According to Niederhauser, more mines are looking to stack dry tailings using filtration (or a filtered cake). "There is a role for a high density thickener in this process as well," Niederhauser said. He cited a coal application that uses a plateandframe press. The mine filters thickened tailings from a high density thickener.
Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.
Coal. From mine face to eliminating tailings ponds, McLanan provides solutions for both surface and underground coal mining in all aspects of the operation. The company offers a full range of feeding, crushing and sampling equipment, as well as washing and dewatering systems that can remove impurities and increase the heating value of your coal.
Alfa Laval decanter centrifuges are the perfect choice for a wide range of solidliquid separation duties in mining and mineral applications. They can replace or complement existing solutions and help boost capacity, reduce tailings volumes, save space and increase the recovery of water, chemicals and your solidliquid separation processes is a straightforward way to cut ...
Fine Coal Recovery from Tailings Impoundment''s. Resource recovery by Dredging. Dredging, as a means of mining or reclaiming is not a new process, for many years it has been used to recover a wide variety of minerals. The recovery of fine coal tailings by dredge however is not all that common.
Water from the coal thickener overflow and disc filter filtrate reports to the clarified water tank (partitioned compartment) to be reused as wash water for the flotation cells. Tailings from the flotation cells reports to the tailings thickener. Tailings Thickener The tailings from the flotation cells will gravitate to a high rate ...
At times, coal mines are also challenged with the issue of product losses flowing from coal fines thickeners. Sometimes referred to as "rafting", less than optimal surface charge conditions prevent coal fines from being totally captured, and valuable product is lost. OptiFlox® is a proprietary system that addresses these operational issues.
FL optimises fine coal circuit. ... at one of New South Wales'' premier open pit coal mines. ... of the reflux classifier and the capabilities of the tailings thickener, which is also being ...
Sep 21, 2009· A customer had multiple coal types, that were processed through the preparation plant. Some of the coal types had different settling characteristics, which affected tailings thickener efficiency ...
Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids. The early methods of thickening employed plain, flatbottomed tanks into which the pulp was fed until the tank was full. The solids were then allowed to settle as long as required, the top liquid was decanted, the settled solids were ...
In mining applications, thickening through sedimentation is applied to both the product and tailings streams to recover water. This water is recycled in the process. Figure 1: Thickening. Particle properties affect the degree of separation that can be achieved with sedimentation. Size, shape, surface chemistry, and solids density all influence ...
Mar 03, 2015· Overview of typical mining operation where slurry water is thickening and slurry is dewatered in a filter press ... Mine Process Overview: Thickening and Pressing ... What are thickeners .
Thickener underflow has traditionally been sent to an impoundment or tailings pond. Paste Thickener Paste thickeners have been placed downstream of conventional thickeners as a result of recent improvements in paste technology.
Dec 03, 2019· I''m suggesting that the most critical aspect of a new mining project is tailings management. ... to manufacture the tailings thickener for this site. ... North Goonyella coal mine .
The Rix''s Creek coal mining operation, part of the Bloomfield Group, set out to improve its onsite coal tailings management as part of its sustainability strategy. This is done in order to reduce water and energy consumption and minimize the surface footprint of waste handling processes.
Thickeners are used for dewatering slurries of either tailings or product. A thickener is a large circular tank that is used to settle out the solid material from the water in the feed is widely used for dealing with slime, wastewater, waste residue in metallurgy, mine, coal, petrochemical industry, building materials, environmental protection department etc.
